Aguero, 25, returned to training this week after recovering from a calf injury that has ruled him out since the 6-3 Barclays Premier League win over Arsenal on December 14.
The prolific forward, who has scored 19 times in 20 appearances before his lay-off, is targeting a return in midweek, with manager Manuel Pellegrini having hinted that Aguero could make a return against Cardiff on Saturday.
"I'll be ready for action this week," Aguero told his official website, www.sergioaguero.com.
"My injury is improving slowly. Recovery's going very well. I'm back to sprinting on the field and moving the ball around.
"I'll be fully recovered by the Cardiff game and depending on how the week's training goes I may be able to show up for a few minutes on the second leg against Blackburn for the FA Cup."
Aguero is keen to make a return to action with City top of the Premier League standings, and still in the FA Cup, League Cup and Champions League.
"We are putting up challenge in every competition this year, the striker said. "Then the World Cup is coming up and I hope to keep my form and the level of my game when it arrives.
"Manuel wants us to have possession, he wants defense to keep the pressure up. Since he arrived, he's been working on improvement and I think the team is shaping up already.
"I'm happy with my tally and my performance. Goals I especially like because they win games and most of them decided a match, so that's what makes me happy."
